Inside Oracle's Data Integration community

Tuesday Jun 07, 2011

System
upgrades, migrations, consolidation and maintenance activities are fact of life
in today’s IT environment, as companies strive to achieve higher
performance, scalability and flexibility. Those activities typically require a “planned
outage" and for systems that support global operations or require 24/7
availability even a planned outage can be disruptive to business.

Currently we see a great demand from customers for consolidating their databases to Oracle
Exadata. As they embark on these projects, they also seek a solution to
avoid interrupting availability of their business-critical systems, as it can
significantly impact revenue, productivity, and customer satisfaction. Oracle
GoldenGate’s real-time, heterogeneous data replication capabilities come
very handy in these migration and consolidation projects.It synchronizes old environment, for example
DB2, SQL Server or an earlier version of Oracle Database, with the new Oracle
Exadata system in real time. While the new environment is prepared and tested,
Oracle GoldenGate captures every new transaction from the production system and
delivers to Oracle Exadata as soon as it is ready. Once the systems are in sync applications and users can be pointed to the Exadata system immediately without any
downtime.

One recent customer that chose Oracle GoldenGate for
migration to Exadata is e-Dialog. They are
part of GSI Commerce Inc., and provide integrated digital marketing solutions
to businesses worldwide. When their message volumes for multichannel marketing
and campaign analytics services started to increase rapidly they decided to
move to Exadata to achieve higher performance. At the same time they had to
ensure business continuity during the migration as any outage would impact
their customers’ access to their services. They used Oracle GoldenGate to
complete the migration in phases over six months. Oracle GoldenGate’s
bidirectional replication capabilities allowed e-Dialog to run the legacy
system along with Exadata concurrently.I

success story to learn how Oracle GoldenGate enables successful migration to
Oracle Exadata.
